Abstract:
OBJECTIVE: To study surgical anatomy of the posterior vagus trunk and its distributaries and the relationship with the left gastric artery in laparoscopic gastrectomy.METHODS: The prospective observational trial included 41 patients performed laparoscopic vagus nerve-preserving gastrectomy admitted between November 13, 2017 and November 16, 2018 in Department of Gastrointestinal Surgery,the First Affiliated Hospital,Dalian Medical University.The classification of the relationship between the posterior vagal trunk and the left gastric artery was determined in laparoscopic surgery. The length of posterior vagal trunk,celiac branch, the parallel part of nerve and left gastric artery,and the length of left gastric artery were measured.RESULTS:The probability of posterior vagus trunk,celiac branch and gastric branch was 100%. The relationship between the posterior vagus trunk and the left gastric artery can be divided into three type about compact type 9 cases(22.0%),intermediate type 25 cases(61.0%)and free type 7 cases(17.0%).The distal margin, proximal margin, length of left gastric artery,posterior vagal trunk,celiac branch and the parallel part of nerve and vessel were(2.7±1.0)cm,(4.9±2.6)cm,(4.0±0.6)cm,(5.1±1.2)cm,(4.2±0.6)cm and(2.1±0.9)cm respectively.CONCLUSION: Getting familiar with the anatomy of the posterior vagus trunk and its distributaries and the relationship with the left gastric artery would be helpful to laparoscopic pylorus and vagus nerve-preserving gastrectomy.
